DETAILED DESCRIPTION
[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0029] Reference Figures 1-9 The present embodiment provides a technical solution: a photovoltaic intelligent public trash can, comprising a box body 100, a compression chamber 110 is opened in the box body 100, the compression chamber 110 is connected to a water collecting tank 320, the water collecting tank 320 is connected to a liquid outlet pipe 410, the liquid outlet pipe 410 is slidably connected to a filter cartridge 400, an evaporating cotton 500 is fixedly connected to the outside of the box body 100, a strip nozzle 550 is connected to the upper part of the evaporating cotton 500, the strip nozzle 550 is connected to a drain pipe 420, the drain pipe 420 is plugged into the filter cartridge 400, the wastewater in the water collecting tank 320 is filtered by the filter cartridge 400, and then discharged to the evaporating cotton 500 through the strip nozzle 550 for natural evaporation.
[0030] After the garbage is placed in the box 100, it is compressed into the compression chamber 110. The wastewater generated during the compression process flows into the water collection tank 320. With the subsequent compression of the garbage, the wastewater gradually accumulates. As the wastewater increases, the wastewater can enter the filter cartridge 400 through the liquid outlet pipe 410. The filter cartridge 400 filters the wastewater so that the solid residue in the wastewater is removed. The filtered wastewater enters the strip nozzle 550 through the drain pipe 420 and is sprayed on the top of the evaporating cotton 500. The wastewater is evenly diffused along the fiber gaps of the evaporating cotton 500 and evaporates with the help of natural wind and sunlight to achieve harmless treatment of the wastewater. At the same time, the environment around the garbage box is kept dry and clean, so that the wastewater after compression of the garbage can be cleaned, saving the internal space of the box 100.
[0031] The water collecting tank 320 is also connected to a plurality of baffles 330 in a linear array at the port facing the compression chamber 110. The arrangement of the plurality of baffles 330 can prevent garbage from entering the water collecting tank 320. The strip nozzle 550 is formed by a rectangular box. The bottom wall of the rectangular box is provided with a plurality of water spray holes 551 in a linear array. The waste water after filtration and deodorization flows to the evaporating cotton 500 through the water spray holes 551. The first filter screen 440, the second filter screen 441 and the third filter screen 442 are connected in sequence from bottom to top in the filter cartridge 400. The bottom of the filter cartridge 400 is fixedly connected to the reversing cylinder 430, and the reversing cylinder 430 is connected to the first pipe 431 and the second pipe 432, the first pipe 431 is connected to the space between the first filter screen 440 and the second filter screen 441, and the second pipe 432 is connected to the space between the second filter screen 441 and the third filter screen 442; the end of the liquid outlet pipe 410 is closed, and a water outlet hole 411 is provided on the side wall near the end, and the end of the liquid outlet pipe 410 is slidably connected to the reversing cylinder 430. In the initial state, the water outlet hole 411 is higher than the top port of the reversing cylinder 430, and the filter cylinder 400 can slide up on the liquid outlet pipe 410 so that the water outlet hole 411 is connected to the lower space of the first filter screen 440, the first pipe 431 and the second pipe 432 in sequence.
[0032] As the filter cartridge 400 is used, the first filter screen 440 at the bottom will become clogged, thereby increasing the flow resistance of the wastewater, but the wastewater is still used, and the flow force of the wastewater is provided by the compression of the garbage. Therefore, when the permeability of the first filter screen 440 is reduced, the flow pressure of the wastewater is applied to the first filter screen 440. At this time, a large amount of wastewater will accumulate in the lower space of the first filter screen 440. The increase in the amount of wastewater causes the filter cartridge 400 to move upward as a whole, thereby driving the reversing cartridge 430 to move upward. At this time, the first pipe 431 on the reversing cartridge 430 is connected to the water outlet 411, and the wastewater is diverted into the space between the first filter screen 440 and the second filter screen 441, and continues to be filtered through the second filter screen 441, ensuring the wastewater treatment efficiency and maintaining the stable operation of the system. By analogy, when the second filter screen 441 is clogged, the filter cartridge 400 continues to move upward, allowing the third filter screen 442 to perform the filtering action. In addition, multiple filter screens can be set in the filter cartridge 400 to increase the service life;
[0033] The mesh sizes of the filter screens in the filter cartridge 400 are the same, ensuring that the flow resistance of the wastewater does not increase suddenly due to the consistent mesh sizes of the filter screens.
[0034] Both ends of the filter cartridge 400 are fixedly connected with sealing cartridges 450 , and the two sealing cartridges 450 are slidably sleeved on the liquid outlet pipe 410 and the liquid discharge pipe 420 .
[0035] A rubber ring can be provided on the inner wall of the sealing cylinder 450 to improve the sealing effect, ensuring that wastewater will not leak during the up and down movement of the filter cylinder 400. At the same time, the rubber ring material is corrosion-resistant, extending the service life of the equipment. A one-way valve can also be provided at the end of the drain pipe 420 to prevent wastewater from flowing back and ensure smooth discharge.
[0036] A plurality of first magnetic rings 451 are fixedly connected to the inner walls of the two sealing cylinders 450 , and a second magnetic ring 452 that cooperates with the plurality of first magnetic rings 451 is connected to both the liquid outlet pipe 410 and the liquid discharge pipe 420 .
[0037] Multiple first magnetic rings 451 are alternately magnetically attracted to the second magnetic ring 452. When the water outlet 411 is connected to the lower space of the first filter screen 440, the uppermost first magnetic ring 451 and the second magnetic ring 452 are tightly adsorbed to ensure that the filter cartridge 400 is stably positioned. When the water outlet 411 is connected to the first pipe 431, the middle first magnetic ring 451 and the second magnetic ring 452 are adsorbed, and so on. Through the arrangement of the first magnetic ring 451 and the second magnetic ring 452, the water outlet 411 is accurately positioned when connected to each filter screen, avoiding filtration failure caused by misalignment, and improving the overall operation stability.
[0038] A bracket 510 is fixedly connected to the box body 100, a accommodating cylinder 520 is fixedly connected to the bracket 510, a rotating shaft 530 is rotatably connected inside the accommodating cylinder 520, a plurality of partitions 540 are fixedly connected to the side wall of the rotating shaft 530, and the plurality of partitions 540 divide the inner wall of the accommodating cylinder 520 into a plurality of spaces for placing activated carbon, and the drain pipe 420 is alternately connected to the plurality of spaces for placing activated carbon inside the accommodating cylinder 520.
[0039] Activated carbon can also be mixed with deodorizers to ensure that the odor of wastewater is reduced. The wastewater filtered through the filter cartridge 400 can flow into the receiving cartridge 520 through the drainage pipe 420, fully contact with the activated carbon, further adsorb residual impurities, and at the same time deodorize the wastewater. The partition 540 is driven to rotate by the rotating shaft 530, so that the activated carbon in multiple spaces can work in turn, avoiding the adsorption saturation of the activated carbon in a single space affecting the effect.
[0040] A gear 531 is fixedly connected to the end of the rotating shaft 530, and a rack 532 engaged with the gear 531 is fixedly connected to the filter cartridge 400, so that when the filter cartridge 400 moves upward, the rotating shaft 530 can be driven to rotate to change the working state of the activated carbon in multiple spaces of the accommodating cartridge 520.
[0041] When the filter cartridge 400 is filtering wastewater, if the internal filter screen is clogged, it means that the filter screen has been used for a long time. Correspondingly, the activated carbon has been used for a long time and needs to be replaced simultaneously. Therefore, when the filter cartridge 400 is moved upward, the rack 532 can drive the gear 531 to rotate, thereby realizing the switching of the activated carbon space, ensuring that the new activated carbon is put into work, maintaining efficient adsorption, extending the equipment maintenance cycle, and ensuring the wastewater treatment effect.
[0042] An installation cavity 130 is also provided in the box body 100. The installation cavity 130 is located on the opposite side of the compression cavity 110. An electric telescopic rod 300 is fixedly connected to the installation cavity 130. A pressure block 310 is fixedly connected to the output end of the electric telescopic rod 300. When the electric telescopic rod 300 is extended, it can drive the pressure block 310 to slide into the compression cavity 110.
[0043] When the control system detects that the electric rotating rod 200 is rotating, it controls the electric telescopic rod 300 to shorten. At this time, the pressure block 310 is away from the compression chamber 110. When the electric rotating rod 200 rotates again, the control system controls the electric telescopic rod 300 to extend. The pressure block 310 is close to the compression chamber 110 again, and the input garbage is compressed into the compression chamber 110, ensuring uniform garbage density and improving compression efficiency. At the same time, it avoids the problem of low storage space utilization of the box 100 due to garbage accumulation.
[0044] A door 150 is hinged on the box body 100, and the port of the box body 100 located below the door 150 is rotatably connected to an electric rotating rod 200. A semicircular shell 210 is fixedly connected to the electric rotating rod 200, and a delivery cavity 211 is provided on the semicircular shell 210. An induction switch 170 is provided on the outside of the box body 100. When a person approaches the induction switch 170, the electric rotating rod 200 rotates one hundred and eighty degrees to cause the semicircular shell 210 to flip over and make the delivery cavity 211 face upward. When the delivery cavity 211 faces upward, the semicircular shell 210 pushes the door 150 to swing up and open.
[0045] When the induction switch 170 senses that a person is approaching the box 100, the control system controls the electric rotating rod 200 to rotate, the semicircular shell 210 flips over, and the delivery cavity 211 faces upward to facilitate the delivery of garbage. The principle of the induction switch 170 controlling the rotation of the electric rotating rod 200 is similar to that of the existing induction opening trash can, which will not be elaborated here.
[0046] A garbage transfer chamber 120 is defined in the box body 100 at the lower portion of the semicircular shell 210 .
[0047] When the electric rotating rod 200 rotates so that the delivery chamber 211 faces downward, the garbage delivered into the delivery chamber 211 slides to the bottom of the garbage transfer chamber 120 due to gravity, and is then pushed into the compression chamber 110 by the pressing block 310 for compression.
[0048] A photovoltaic panel 160 is fixedly connected to the upper surface of the box door 150 , and a moving wheel 140 is provided at the bottom of the box body 100 .
[0049] The photovoltaic panel 160 absorbs solar energy and converts it into electrical energy, which provides power for the electric telescopic rod 300 and the electric rotating rod 200 in the box 100, achieving energy self-sufficiency, reducing operating costs, and improving environmental benefits. The electrical energy of the photovoltaic panel 160 is stored in the built-in battery to ensure normal operation of the equipment on rainy days. The setting of the mobile wheels 140 makes the box 100 easy to move and adapt to the needs of different places.
[0050] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
